The 2020 GMC Vans Savana 3500 remains one of the few full-size vans that stayed focused on heavy-duty commercial and fleet use rather than crossover styling. Its long-running, body-on-frame formula made it a familiar choice for cargo hauling, passenger service, and upfit work where durability and payload matter. For this exact van, tire fitment is refreshingly straightforward: 245/75R16 radial on a 16-inch rim across the covered Savana 3500 lineup. That simplicity shifts the decision toward selecting the right tire type, sidewall treatment, and use profile, especially for owners balancing work duty, replacement fitment, and everyday road manners.
Which Tire Size Is Right for The 2020 GMC Vans Savana 3500
The 2020 GMC Vans Savana 3500 uses one primary tire size: 245/75R16 radial on a 16-inch rim. That same size carries across Base, LS, and LT models, so the main decision is not which factory size applies, but which tire best matches the van's working role, wheel specifications, and preferred sidewall and tread style.
A 245/75R16 tire uses a 245-millimeter nominal section width, a 75-series aspect ratio, radial construction, and a 16-inch rim diameter. On the 2020 GMC Vans Savana 3500, this is the primary fitment and it suits the van's heavy-duty full-size role with a modern radial layout. Available choices in this size can still differ in character, including details such as raised white letter sidewalls and an all-terrain tire series from BFGoodrich. Choosing within 245/75R16 means confirming wheel width, intended load use, and whether the van remains on its original wheel and suspension setup.
Tire fitment is consistent across the covered 2020 GMC Vans Savana 3500 sub-models. That makes selection simpler, but checking the exact sub-model still helps confirm that the van has not been altered with different wheels or a specialized upfit.

2020 GMC Vans Savana 3500 Base
The Savana 3500 Base uses the same 245/75R16 radial fitment as the rest of the covered lineup. Tire selection comes down to matching that size to the van's actual wheel width, load use, and preferred tread and sidewall presentation.
The Savana 3500 LS shares the 245/75R16 radial tire size used across this model range. That gives LS owners a straightforward path: stay with the correct size, then compare tire construction details, sidewall style, and service-duty priorities.
The Savana 3500 LT also uses 245/75R16 radial tires on a 16-inch rim. For LT owners, the practical choice is evaluating how the available tire suits passenger, cargo, or mixed-duty use while confirming wheel compatibility before installation.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:

Tire Size & Fitment
What tire size fits a 2020 GMC Vans Savana 3500?
The 2020 GMC Vans Savana 3500 uses 245/75R16 radial tires. This is the primary size for the covered Base, LS, and LT sub-models, and it fits a 16-inch rim. For most owners, that means the size question is simple and the real comparison starts after the correct size has been confirmed.
Selection still should not stop at the sidewall code alone. Check that the van still has the correct 16-inch wheels, confirm wheel width, and make sure any cargo, passenger, or upfit use is supported by the tire's specifications. A van that has been modified for commercial service can need closer inspection before replacement.
What size rim does a 2020 GMC Vans Savana 3500 use?
The 2020 GMC Vans Savana 3500 uses a 16-inch rim with its 245/75R16 tire size. A matching product in this fitment is built for a rim width range of 6.5 to 8.0 inches, which helps explain why wheel width matters in addition to diameter when choosing a replacement tire.
Rim diameter is the first check, but it is not the only one. A 16-inch wheel that falls outside the tire's approved width range can affect how the tire sits and performs. Owners should also verify that the van has not been changed to aftermarket wheels, especially on work vans that may have seen fleet or contractor use.
Do all 2020 GMC Vans Savana 3500 sub-models use the same tire size?
Base, LS, and LT versions of the 2020 GMC Vans Savana 3500 all use the same 245/75R16 radial tire size. That shared fitment simplifies replacement because the covered sub-models do not split into different primary sizes, rim diameters, or construction types at the model level.
Even with shared factory sizing, the van in front of you should still be checked before ordering tires. Commercial vans are often repurposed, and changes to wheels, suspension components, or body equipment can affect practical clearance. Confirming the current setup is especially important if the Savana has seen fleet service or specialty conversion work.
Choosing the Right Tire
What should I consider when choosing a 245/75R16 tire for a 2020 GMC Vans Savana 3500?
Start with the correct 245/75R16 size, then compare the tire's construction, load specification, and wheel-width compatibility. For the Savana 3500, those details matter because this is a heavy-duty full-size van that may be used for cargo, passengers, service work, or mixed-duty driving rather than light personal use alone.
Tread style and sidewall treatment also shape the decision. An all-terrain design may suit owners who see rougher surfaces, while the wheel setup still needs to match the tire's approved range. Matching the tire to how the van is actually used is more important than choosing by size code alone.
What sidewall styles are available for 2020 GMC Vans Savana 3500 tires?
A raised white letter sidewall is available in the 245/75R16 fitment for the 2020 GMC Vans Savana 3500. That gives the tire a more aggressive, utility-oriented appearance than a plain black sidewall and can matter for owners who want a stronger visual tie to truck and off-road tire styling.
Sidewall style should still be treated as an appearance choice layered on top of fitment and service needs. On a Savana 3500, the tire still has to match the van's wheel size, wheel width, and intended use. A sidewall treatment can change the look noticeably, but it does not replace proper load and fitment checks.
What brands offer tires for the 2020 GMC Vans Savana 3500?
BFGoodrich offers a 245/75R16 fitment for the 2020 GMC Vans Savana 3500 through the All-Terrain T/A KO2 line. That gives this van a recognizable option within the correct size, with radial construction and a heavier-duty light truck profile that aligns with full-size van use.
Brand alone should not be the deciding factor. Compare the tire's load capacity, approved rim-width range, tread style, and sidewall presentation against the way the Savana is actually used. A passenger shuttle, cargo van, and contractor van may all share the same size while placing very different demands on the tire.
Restoration & Appearance
Which tire should I choose for a period-style 2020 GMC Vans Savana 3500?
A period-style approach on a 2020 GMC Vans Savana 3500 usually means staying with the correct 245/75R16 size and choosing a tire whose visual character suits the van's heavy-duty, truck-based appearance. In the available fitment, a BFGoodrich All-Terrain T/A KO2 offers a more rugged light-truck presentation than a highway-oriented design would.
Appearance should still follow fitment, not override it. Confirm the 16-inch wheel setup, approved rim width, and the van's actual use before deciding on a look-driven option. Since this is a modern commercial-era van, exact originality questions are better resolved through vehicle-specific references if that level of accuracy matters.
How does tire construction affect the appearance of a restored 2020 GMC Vans Savana 3500?
On the 2020 GMC Vans Savana 3500, the primary fitment is already a modern radial, so construction does not create the same bias-ply-versus-radial appearance debate seen on older collector vehicles. Visual character comes more from tread pattern, sidewall style, and overall light-truck presentation than from the basic construction type itself.
That means a restoration-minded or preservation-focused owner should pay close attention to the tire's styling cues within the correct 245/75R16 size. Raised white letter sidewalls and an all-terrain tread can make the van look more rugged, while a more restrained design would keep the appearance closer to a straightforward work-van theme.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 GMC Vans Savana 3500?
Yes. Even though the 2020 GMC Vans Savana 3500 uses 245/75R16 tires from the factory, aftermarket wheels, suspension changes, body equipment, and commercial upfits can alter how that size fits in practice. A van that has been lowered, lifted, or refitted for work may need more than a simple size match.
Check wheel diameter first, then confirm wheel width, tire clearance at full steering travel, and space around the fenders and suspension. Service bodies, interior conversions, and heavy-use modifications can all affect the tire environment. That extra verification is worthwhile before replacing tires on any work-oriented full-size van.
What should I inspect before driving a 2020 GMC Vans Savana 3500 on new tires?
Before road use, inspect wheel condition, lug hardware, valve stems, and tire pressure, then look over the suspension and steering components for looseness or wear. On a 2020 GMC Vans Savana 3500, it also makes sense to confirm that the new 245/75R16 tires are mounted on the correct 16-inch wheels and seated properly.
A short test drive should be followed by another visual check for rubbing, uneven stance, or any sign of interference under turning or load. Because these vans often work hard, owners should also consider the vehicle's cargo or passenger role before regular service. New tires perform best when the rest of the chassis is in equally sound condition.
How often should tires on a 2020 GMC Vans Savana 3500 be inspected?
Tires on a 2020 GMC Vans Savana 3500 should be inspected regularly, with extra attention before longer trips, after heavy hauling, or whenever the van has been sitting for extended periods. Look for uneven wear, cuts, punctures, sidewall damage, cracking, and any loss of pressure that could point to a developing problem.
A full-size van can place steady demand on its tires, so routine inspections are part of staying ahead of fitment and safety issues. Pressure should be checked consistently, and any sign of unusual wear should prompt a closer look at alignment, suspension condition, or wheel setup. Frequent inspection matters even more on fleet-used or heavily loaded vans.
